Case Reports
Use of a sandwich technique to repair a left ventricular rupture after mitral valve replacement.
One difficulty with external repair of left ventricular rupture after mitral valve replacement is collateral bleeding in friable myocardium adjacent to the rupture. The bleeding is caused by tension on the closing sutures, whether or not pledgets have been used. We report the case of a 69-year-old woman who underwent an uneventful mitral valve replacement. ⋯ This simple technique enabled closure of the defect and avoided collateral tears that would have compromised an otherwise successful repair. Two years postoperatively, the patient had normal mitral valve function and no left ventricular aneurysm. In addition to reporting the patient's case, we review the types of left ventricular rupture that can occur during mitral valve replacement and discuss the various repair options.

Review Case Reports
Emergent surgical pulmonary embolectomy in a pregnant woman: case report and literature review.
Acute pulmonary embolism is a leading cause of death during pregnancy and delivery in the United States. We describe the case of a 25-year-old woman who presented in cardiogenic shock in week 38 of her first pregnancy. ⋯ Mother and child were doing well, 27 months later. In addition to presenting our patient's case, we discuss the other relevant reports and the options for treating massive pulmonary embolism during pregnancy.

Multicenter Study Comparative Study Observational Study
Perioperative outcomes after on- and off-pump coronary artery bypass grafting.
Although numerous reports describe the results of off-pump coronary artery bypass grafting (CABG) at specialized centers and in select patient populations, it remains unclear how off-pump CABG affects real-world patient outcomes. We conducted a large, multicenter observational cohort study of perioperative death and morbidity in on-pump (ON) versus off-pump (OFF) CABG. We reviewed Veterans Affairs Surgical Quality Improvement Program data for all patients (N=65,097) who underwent isolated CABG from October 1997 through April 2011 (intention-to-treat data were available from 2005 onward). ⋯ A subgroup intention-to-treat analysis yielded similar but smaller outcome differences between the ON and OFF groups. Off-pump CABG might be associated with decreased operative morbidity but did not affect operative death, compared with on-pump CABG. Future studies should examine the effect of off-pump CABG on long-term outcomes.

Massive pulmonary embolism is associated with mortality rates exceeding 50%. Current practice guidelines include the immediate administration of thrombolytic therapy in the absence of contraindications. However, thrombolysis for pulmonary embolism is said to be absolutely contraindicated in the presence of recent hemorrhagic stroke and other conditions. ⋯ Despite this practice guideline, we administered tissue plasminogen activator systemically in order to save the patient's life. This therapy did not evoke intracranial bleeding, and the patient was eventually discharged from the hospital. Until guidelines specific to venous thromboembolic disease are developed, we think that the current contraindications to thrombolysis should be considered on an individual basis in patients who are at high risk of death from massive pulmonary embolism.
